Annotation checklist
This guide is meant to be a checklist for annotating categories of embryonic development in Montipora capitata using NIS-Elements BR.
For a basic introduction to using NIS Elements Annotation & Measurement tool, check out this elearning video.

and click ont he three dots to change font color to white and background to transparent. Keep all other settings the same.Using the annotation & measurement tool, insert text to label via numbering 1-n each embryo at its upper left quadrant. Do not number debris.
Click on the taxonomy shape icon under

Right click inside the table to access
Taxonomy Options
Set number of classes to 10
egg
cleavage
4 to 16 cell
32 to 64 cell
prawn chip
early gastrula
debris
malformed
typical
torn
Click on taxonomy label and label each embryo with a selection from phase (egg, cleavage, 4-16, 32-64, prawn chip, or early gastrula) and proper selection from status (debris, malformed, typical, torn)

egg (unfertilized oocyte)

32-64 cell stage
prawn chip (9 hours post fertilization)
early gastrula (14 hours post fertilization)
Note that the phases in bold are the ones that we expect our embryos to be in based on hours post fertilization that they were preserved in 4% ZFIX. In this study, we conducted bundle-bundle crosses in 20mL of treatment solution (either a 0.22 micron filtered seawater control
, or three increasing levels of PVC leachate derived from microplastics: 0.01 mg/L PVC leachate low
, 0.1mg/L PVC leachate mid
, or 1mg/L PVC leachate high
).
